Vostro 1400 overclocking, its crazy.

Here are some synthetic benchmarks for an overclocked 8400m GS per Jason...

core/memory - 600/750

3dmark03 - 8399
3dmark05 - 3697
3dmark06 - 1530
aquamark - 61,367

 

to bring the conclusion to this saga, I ask of devilsknight and others who are really into this topic to stop posting various stats and finally check the temperature of the system with a thermometer cause it's nonsense posting 19 pages of posts without getting anywhere. Different temp checking programs offer different results (and they are still different than real ones IMO).

I remember that someone (maybe ChaosKye) tried to put all the results together and get the point out of all this. Don't get me wrong, I am extremely grateful to you all, people, cause you moved the limits in 'vostro science' and encouraged me and probably others towards buying it (it seems that it's monstrously durable whilst OCing it).

So, all sumed up, get the temperature with the thermometer, and then go on cause up to this point this is almost all waste of webspace.

 

The problem with measuring the temperature with a thermometer, is that your not going to get the GPU core temperature. You will only be able to measure the metal that is right around the GPU core. And that could be 10-20C less than the actual core temp.

People have been saying that "Oh your going to fry your GPU" and "Your temperatures are way to high." Stuff like that. But what you have to take in consideration is: When you overclock a graphics card and adjust the core and memory clock the temperature will no doubt go up. And a very good indicator of how far is to far is when you start seeing artifacts. Artifacts are caused by two things: either the temperature of the card is too high, or the card is not getting enough voltage to operate at the extreme clock settings.

That said, when some of us overclock our 8400GS as long as we are not seeing artifacts, the card should still be running at a safe temperature and getting the voltage it needs. In conclusion: If you don't see artifacts, you should be fine!

I had an nVidia 6200 desktop card a while back. I pushed that thing and it was often in the 90's when gaming. No artifacts or anything, ran hot, but ran strong for over a year until I sold it.

 

what driver version have you, and where can I get it????
I have in 3dmark03 -7190 (core 554 mem 839 and processor T7700 2,4Ghz)
How to expalin it?

 

Remember, the threshold temperature is somewhere around 130C. 90-100C may sound like a lot, but is within the design tolerance.

 

Are we sure of that 130C? I mean becuase it's ok for desktops does that also mean it's ok for laptops?

Also is it possible that the temp doesn't damage the gpu but may damage surrounding components of the laptop (like melt a support or warp the keybaord or something)?

 

The driver is 158.36.

I may go splurge tonight at radio shack and get an IR thermometer ($50) or a different (See "Cheaper") thermometer to verify the correct temp for the GPU.

 

I'd also like to know an answer for Devedander's question.

@Jason
Well then, if we know for sure how great is the temperature loss while measuring it with thermometer then we can still measure it with it and add approximate loss to the sum. Plus if we know the type of the metal the thermometer will lean on we can easily calculate it's thermal admittance and get more precise results. It ain't hard.

Can you explain me more about these 'artifacts'? Are they some sort of spots that appear on the screen whilst working with OCd GPU?

Can you also tell me (approximately of course) how long will devilsknight or zero's vostro last with these OC stats?

@devilsknight, zero
Can you please post number of hours your battery lasts (9 cell preferrably) while overclocked (doing some light work like net surfing or MSWord and hardcore gaming)?

 

Here it is, what we have all been waiting for... IR Thermometer temperatures for the 8400m GS with the 158.32 drivers.

Idle
I8kFanGUI - 59C
Nvidia Monitor - 69C
IR Thermometer - 57C

Stressed - Stock Speeds
I8kFanGUI - 79C
Nvidia Monitor - 89C
IR Thermometer - 67C

Stressed - 600/750
I8kFanGUI - 80C
Nvidia Monitor - 90C
IR Thermometer - 68C

This was done using a $50 IR thermometer from Radio Shack and taking the highest reading I got on the heatsink. It didn't give me a laser dot where I was getting temps so I held it as close as possible and moved it around to get the highest temps I could. I tried to get the same, or similar result multiple times to verify the temperature. The laptop was turned on it's side and the covers removed to access the heatsink.

I'm going to go return the thermometer now so unfortunately I can't take more temps.

It is hard to get a direct Heatsink reading without removing the whole bottom of the laptop, which I am not about to attempt. All of these readings were off of the side of the heatsink exposed with the memory cover off. Hope this provides some clarification for everyone.

 

Ok now that people have overlcoked their cards can someone see if the Bioshock demo actually runs on the 8400 GS?
